In short, I think you are on the right track with Pitch Dredge for them, but you might want to consider some adjustment here. Longer response...
If they have Orchard and Oath then you will need a way to stop Oath from activating, or a way to answer the target (Ray of Revelation, Karakas, or a Force/Unmask). Dredge has too much difficulty trying to be a consistently a turn 2 deck, and that can actually still be too slow for them (making the only good answers having an opening hand Karakas or Force/Unmask).
As long as you have a way to win in 1 turn then just keeping your board clean, and biding your time works extremely effectively against an Oath if they don't have both Orchard+Oath. That makes non-may effects like Amalgam and Bridge from Below worse in that match up, while Narc/Ghast/Ichorid/ect are much better in those matchups. That said, winning in 1 turn is certainly much easier with a large number of Dread Returns, and either Sun Titan or Griselbrand to set up your kill.
This matchup isn't complicated. If you have a good plan for Wasteland its probably a good match up (Loam / Pet field), if you don't then its not going to be a good matchup.
I think this is where Pitch Dredge shines. Jeskai in my experience usually runs Rest in Peace, which is almost impossible to overcome if it resolves. Your best shot is stopping it before that happens. This deck can also run a variety of different Dredge hate and having flexible anti-hate really helps.
Ancient Grudge, Ancient Grudge, and more Ancient Grudge. Along with the whole good answer to wasteland thing (Loam / Pet field). Pitch is not the best against them as you can't really beat them by just stopping one spell so you have to look at some complementary pieces to cover that match up.
